Page History
This page provides information on the V-Ray Mesh Light.
Overview
V-Ray Mesh Light can create light sources that have volume and shape without the need to use self-illuminated objects and global illumination. It is useful for representing light sources that are not planar or spherical, such as string lights or lanterns.
If the Mesh Light is close to other surfaces in the scene, it is best to use it with GI enabled. That way V-Ray can use combined direct and GI sampling of the mesh light. Without GI, the light might produce noisy results for surfaces that are very close to it.
V-Ray Mesh light(s) can be instanced by using Array or Alt+drag the light object in the Rhino viewport.
